[General] Handle on pre-placed objects

[sethmachine]

Hi,

How do we find the handle on a pre-placed object?

e.g. I put a footman on the map. I want to now manipulate that footman. What is its unit reference value? I tried clicking on it and looking in the object manager but it doesn't telling me the raw value.

If you are talking about the handle id of that specific unit then you have to set it to a variable first then get the handle id to use that.

If you select your footman in editor you can see his name at bottom, which unit is selected.

For example, Selected: Footman 0013

Then in trigger you have to write: gg_unit_hfoo_0013

gg_unit_ is always for preplaced units + hfoo (footman) + number of unit (depends how many units have been created before in editor)

Thank you, this makes sense!

I will just add that the variable may mot be created, in that case, you have to "invoke it" by using any GUI action on that unit(Kill Unit and select it for instance), you can remove the GUI action afterwards

What about other objects? Destructibles are called what?

 

[IcemanBo]

gg_unit for unit

gg_dest for destructables

You can test it by yourself. Make a GUI action "Kill - Destructable" for example. -> convert trigger into custom script and voila there it is.

I followed the suggestions, including invoking the variable, but I still get a bunch of errors.

library City initializer init

globals
    constant real CITY_CENTER_X = -12826.9
    constant real CITY_CENTER_Y = 12474.9
    destructable CITY_GATE = gg_dest_DTg5_0008
endglobals

private function init takes nothing returns nothing
    call KillDestructable(CITY_GATE)
    call SetDestructableAnimation(CITY_GATE, "death alternate")
endfunction
endlibrary

It claims that gg_dest_DTg5_0008 is multiply defined and then it claims that it doesn't exist!

How on earth can I simply open a preplaced gate...

If I change it to a scope, the errors go away but the gate still doesn't open...

You can't assign a global to it in the global block (or at least, it doesn't make much sense to do so). In the generated map script, the globals are moved into the globals block, so you'll end up with something like this:

globals
    constant real CITY_CENTER_X = -12826.9
    constant real CITY_CENTER_Y = 12474.9
    destructable CITY_GATE = gg_dest_DTg5_0008
    // ... some other globals
    destructable gg_dest_DTg5_0008 = null
endglobals

Note that the JASS parser reads the script from up to down, and it hasn't encountered gg_dest_DTg5_0008 yet (it is declared later). So it'll immediately throw an error. When you change it to a scope, it might order it after the gg_dest_DTg5_0008, but keep in mind that the variable either points to null or is uninitialized, so assigning CITY_GATE to it will just make CITY_GATE point to null (or it might stop the thread, if the variable is uninitialized).

The generated globals are set in a separate function, which is called on initialization. As such, you should assign CITY_GATE to it on initialization (or after a 0 second timer, whichever works):

library City initializer init

globals
    constant real CITY_CENTER_X = -12826.9
    constant real CITY_CENTER_Y = 12474.9
    destructable CITY_GATE
endglobals

private function init takes nothing returns nothing
    set CITY_GATE = gg_dest_DTg5_0008
    call KillDestructable(CITY_GATE)
    call SetDestructableAnimation(CITY_GATE, "death alternate")
endfunction
endlibrary

Or you can simply use gg_dest_DTg5_0008, but it makes the code look kinda ugly so just stick with CITY_GATE (or assign a local to the gg global).

Well it worked when I used the BJOpenGate function, I guess because it was also a scope by then?
